UNITED STATES PATENT SAMUEL T. FERGUSON, OF MINNEAPOLIS, MINNESOTA.

IMPROVEMENT IN COLTERS.

Specification forming part of Letters Patent .No. 172,872, dated February 1, 1876; application filed October 6, 1875,

To all whom it may concern.-

Be it known that 1, SAMUEL T. FERGUSON, of Minneapolis, Minnesota,' have invented certain new and useful Improvements in Gaster-Oolter for Plows, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings making a part of this specification, in which Figure l is a perspective view of a castercolter with my improvements attached. Fig. 2 is a cross-section of the same.

The object of my invention is to provide a cheap, simple, and easilyadjusted castercolter for plows, and one which, while having a lateral and vertical adjustment, can also be adjusted atany point on the beam desirable; and it consists in the combination and arrangement of parts hereinafter described and claimed.

To enable others skilled in the art to make and use my invention I will proceed to describe the exact manner in which 1 have carried it out.

In the said drawings, A represents a sleeve fitting on the spindle, and which :can be adjusted vertically to any desired position on the I spindle b by means of the thumb-screw I. Attached to the sleeve A is a slotted projecting arin, B. Passing around the beam 0 is the yoke a, whose ends pass through the slot in the arm B, and are provided with screws e and nuts 0 c, by which means the beam 0 may be secured to. the arm B at any desirable point, and thus adjust its length.

'By means of theslot in arm B a lateral adjustment is given to the beam.

This colter-caster can be attached to either iron, steel, or wood beams without boring or otherwise injuring the beams in any manner, and can be readily transferred from one plow to another.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

In a caster-colter, the sleeve A, provided with the thumb-screw l, and having the slotted horizontal arm B, in combination with the yoke (1, provided with the screws and nuts '0 c, substantially as and for the purpose set forth.

. In testimony that I claim the foregoing I have hereunto set my hand.

SAM. T. FERGUSON.
